There is also an ongoing investigation into a bank robbery that occurred at 70th Street and Appleton Avenue days before she disappeared.

Kevin Blackburn, 25, of Milwaukee, appeared in court Wednesday facing bank robbery charges in connection with a robbery of the Educators Credit Union on May 7.

Charges have also been filed against another suspect, who is still at large, 31-year-old Ricardo Perkins.

Police have not said if they suspect a connection between the robbery and the disappearance of Jessica Benson.

Benson's name is mentioned in the criminal complaint against Blackburn as one of the tellers who took money from her drawer and placed it in a tube feed that was sent out to the robbers, who had threatened to set off a bomb they if they didn't comply.

"I know that the FBI was supposed to be picking up the case," Benson's sister, Judy Beyer, said.

WISN 12 News asked Beyer if she had any reason to suspect the robbery might be connected to her sister's disappearance.

"I'm not exactly sure, but there is always a chance and a possibility that maybe it is, yes," Beyer said.

Beyer said she believes Benson's boyfriend might somehow be acquainted with the suspects. She said she also believes investigators are getting closer to finding out what happened to her sister.

"Hopefully, they are getting closer. I hope that it's almost done, and it's coming to an end. Every day now since the FBI picked it up, I feel a little bit better. I only say that because I feel like maybe, you know, they have more ways to try to find things than what the police," Beyer said.

There is a reward for any information leading to Benson's whereabouts. Anyone who knows anything is asked to call Milwaukee police.

Family and friends held a vigil for Benson on Wednesday night at the Educators Credit Union.
